Dynamic models to simulate tearing of soft elastic bodies are an essential element of various medical and surgical training simulators. These models are also finding increased use in film and gaming applications, where control of the quality and style of the final output is highly valued. There is a general lack of models specifically designed to control tearing patterns, and in this paper, we present our work towards a soft-body tearing method that provides simple parametrizations to control the tear independently from the elastic properties of the soft body simulation. Our parameters can influence how clean-cut or jagged the tear is, in addition to allowing anisotropic influence using an embedded fibre model in the elastic body. We also aim for a real-time implementation suitable for interactive environments. Our meshless solution is discussed in a context that is aware of the importance of unified physics solvers.
